- My invention relates to a motometer light.

ing attachment, and has for its object to, at-

inate the liquid" tube 'at fvnight.

Another purpose of the improvement is to.

- provide aQu nit ary attachment thatcan be manufactured a't a loweost," and quickly 9.8; sembled in operative relationship upon a motometerp' 'I Still a further object of the invention is to afford an arrangement that will illumlnate the liquid tube of the moton ieter 'at ni htf at the same time 'protecting ,the yes 0 a driver against glare or light comi'ng directly from the illuminating meanslf I Anadditibnal object of the improvement is to afford a structure of fefwfparts'jthat can be housed withinitli'e conventionaltype of motometer so as in no-way to interfere with" the customary use'f thelatter or to detract from its appearance.

Another pi 'fp'o'se of the improvement-is support .5 is preferably curved along. its

the housing 1 and retainingring ii ofthe motometer. The support 5 isheld in place by posed upon thesupbort 5, and thescrews 7 uwhich are used to hold the retaining ring?) in place engagethe openings 8 in the support 5 and thus retain the latter as indicated in Figures 1 and 2.

In the drawings:

Figure 5 is a sectional view on the line 5'5 of Figure 3, and

Figure 6 is a sectional view on line 66 of Figure 3.

In the embodiment illustrated, which includes a preferred arrangement of the invention, 1 designates the housing of a con- \entional type of motometer including a liquid tube 2 and retaining ring 3 which holds in lace the rear crystal, while 4- is the usual sig t opening in the front crystal.

conducting member also conn'ected to the lamp socket and preferably in the form of a flat strip adapted to extend under the retaining ring 3. as shown in Figures l and 2.

I

The construction described is of extreme simplicity. and has the advantage of comprising but a single unit which can be quick-- lv attached in proper position in. a conventional motometer by me1'ely removing the retaining ring and rear crystal of the latter to permit of placing the supporting plate 5 under the retaining ring, as shown. in Figures 1 and 2. Upon repositioning the crystal and retaining ring and securing the latter in place. the illuminating attachment is ready for operationwhen connection is-made through the plug 17; i

see of the following claims. c P3 cise details herein illustrated, and this ap plication is intended to cover other mo ictications and changes such as may come within the spirit of my improvement or ,the

aim:

1 A motometer li hting attaclnnent comrlsing ,a removable supporting plate, a

amp socket secured to the front face of the supporting plate, and a fiat conducting strip connected to the lamp socket and termiuat- .ing in a switch socket ada ted to be located outside the motometer, saic supporting plate serving to shield the eye of a driver from the lamp.

2. A motometer lighting attachment comprising a supporting plate, a lamp socket permanently attached to one face of said plate, and light deflecting flanges along the inner edges of the late.

3. A motometer ighting attachment comprising a supporting plate, a lamp socket permanently attached to one face of the plate, light deflecting flanges along the inner edges of the plate, and a flat conductin member connected to the lamp socket an terminating in a switch socket adapted to be located outside the motometer.

4. The combination with a motometer including a retaining ring for a. rear crystal, of'a supporting plate remorabl held in ositio "by the retaining ring and arrange in la te paralle "thereto, a lamp socket setb the cc of said plate, and a connected to the lamp p, hini tion with a motometer including'u eta'i'ning ring for a rear crystal, of a supporting plate, the outer edges of the supporting plate hem curved to conform to the retaining ring an held in place thereby, the inner edge of said plate extending par;

the retaining allel to 'tbe liquid tube for a portion of the latter and curving thence around the sight opening, a lamp socket permanently attached to the front face of the plate, and a conducting member connected to the lamp socket and extending under the retaining ring, terminating outsidev the motometer m a switch socket.

6. The *1 .nbination with a motometer including a retainin ring for a rear crystal, of a supporting p ate, the outer edge of the support ng plate being curved to conform to.

the retaining rim and held in place thereby,

the inner edge of sa id plate extending paralcludin a retaining ring for a rear crystal,

(1 In place by the re-- of a piiite removably he taining ring and arranged in a plane parallel thereto, and 'a lamp socket carried by the plate, said plate functioning both to support the lam socket and to shield the eyes of a driver .rom light cast by a lamp in said socket.

8. The combination with. a motometer includinga retaining ring for a rear crystal, of a support located within the motome'ter and relnovably held in place by said retam ing tin", and a lamp socket attached to' the forwar face of the support, the'latter comprising a plate arranged'i'n learnt a lamp socket and functioningp shield the eyes of a driver from light of the'la'mp. v

In witness whereof, I havliereunto signed my name. c
